Panchang in Ipameri, Goiás, Brazil Sun 15 Sep 1974

Amavasya follows the tithi at sunrise. Amavasya runs from 03:11 on Sun 15 Sep to 23:45 on Sun 15 Sep, so it holds sunrise only on Sun 15 Sep, at 06:08. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 06:08 here. Chaturdashi ended at 03:11, before it. Amavasya ends at 23:45, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

The night of Sat 14 Sep ran from sunset 18:07 Sat to sunrise 06:08, 12 h 1 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:08 to 18:07, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 06:07 Mon, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 2 at 136°40′. It leaves at 19:25, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 148.6° + 138.4° = 287°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 15:38, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada runs until 13:27, when the lead reaches 354°; Nagava until 23:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:08 to 06:07 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 16:01 Sat to 15 Sep 23:45 the Sun stayed in Simha, entering Kanya at 16 Sep 15:33 Mon, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada itself.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 15 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1974, 18:23 Sat. Since then the Sun has moved 169.2° round the stars. Vikram Samvat numbers that year 2031; Shaka Samvat numbers it 1896.
